Adaptive computing is one of the power reduction methods to take full advantage of reconfigurable devices. The approach, for example in mobile phones which require long-lasting batteries, makes the device choose a suitable circuit image from ones with different power consumption and error correction, as signal-to-noise ratio changes. In this paper, We have implemented five Viterbi decoders of which constraint length K ranges from 3 to 7, and built a simulation environment of wireless communication to research the effectiveness of the adaptive computing on the DRP-1, the first silicon implementation of Dynamically Reconfigurable Processor(DRP). We have confirmed that its throughput varies from 4.71 Mbps to 9.95 Mbps and its power consumption does from 428.93 mW to 1028.97 mW at the fixed throughput rate 4.71 Mbps. |
